Multisampling is fully available in ES 3.0+ so extend the condition.
(well technically we should check for the relevant extensions on GLES2
too since embedded/mobile devices will have it, but let's leave that for later)

Similarly, forcing ES 2.0 for the shared context when the original was ES 3.x is
not necessarily a good idea. So do like desktop GL and request the same version.

CanvasContext::getUniformLocation returns 0, if the

check for 0 in the uniform* functions to avoid crashes.

This is already done for most of the uniform* functions. This
commit introduces the remaining checks.
